Oxygenated hemoglobin absorbs weakly in the red (hence its red color) and strongly in the near infrared, whereas deoxygenated hemoglobin has the opposite absorption. This fact is used in a “pulse oximeter” to measure oxygen saturation in arterial blood. The device clips onto a person’s finger and has two light emitting diodes (i.e., LEDs) – a red (660nm) and an infrared (940nm) – and a photocell that detects the amount of light transmitted through the finger at each wavelength
a)Determine the frequency of each of these light sources.
b)If the intensity of the beams is 1.00X10-6 Watts/m2 , calculate the peak electric and magnetic fields of the light supplied by the LEDs.
Sunburn produces cell damage in the skin. Why is ultraviolet radiation capable of producing this damage, while visible radiation, even if more intense, is not?

- Speculate as to why UV light causes sunburn, whereas visible light does not.arrow_forwardUltraviolet (UV) radiation is a part of the electromagnetic spectrum that reaches the Earth from the Sun. It has wave-lengths shorter than those of visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320 nm to 400 nm. Both the U.S. Department of Health and Human Services and the World Health Organization have identified UV as a proven human carcinogen. Many experts believe that, especially for fair-skinned people, UV radiation frequently plays a key role in melanoma, the deadliest form of skin cancer, which kills more than 8000 Americans each year. UVB has a wave-length between 280 nm and 320 nm. Determine the frequency ranges of UVA and UVB.arrow_forwardIf everything radiates electromagnetic energy, why can we not see objects at room temperature in a dark room?arrow_forward

Explain.arrow_forwardHow can treating food with ionizing radiation help keep it from spoiling? UV is not very penetrating.

- The operating temperature of an indirectly heated filament of a vacuum tube is around 1050K. At what wavelength will it radiate maximum? Given b=0.288cm K.arrow_forwardSuppose you need to image the structure of a virus with a diameter of 50 nm. For a sharp image, the wavelength of the probing wave must be 5.0 nm or less. We have seen that, for imaging such small objects, this short wavelength is obtained by using an electron beam in an electron microscope. Why don’t we simply use short-wavelength electromagnetic waves? There’s a problem with this approach: As the wavelength gets shorter, the energy of a photon of light gets greater and could damage or destroy the object being studied. Let’s compare the energy of a photon and an electron that can provide the same resolution. For the electron with a de broglie wavelength of 3.5 nm, what is the kinetic energy (in eV)?arrow_forwardSuppose you are standing in the dark and facing a 20-W LED bulb 100 meters away. If the diameter of your pupils is about 8 mm under these conditions, about how many photons of visible light enter your eye every second? (Hint: the answer is about 6 billion photons per second)arrow_forward
- What is the wavelength, in nm, of a photon with energy (a) 0.30 eV, (b) 3.0 eV, and (c) 30 eV?

Why not just use extremely short electromagnetic waves, which are much cheaper to generate?arrow_forward
